I've played Rock Band since Rock Band 1, and I have around 800 songs in my collection, and I can FC around 80%+ of them on guitar. However, I'm having trouble getting 5 stars on songs on Blitz, I just want to know if I'm doing things right. I try getting each lane to its maximum multiplier, and obviously try to keep combo (blitz mode) for as long as possible, but I seem to not even get 5 stars (are there even gold stars in this game? I'm using 2x multiplier and the drum buffs, sometimes the flame one if I have the coins to get it. What am I doing wrong?
